Japan's Hayabusa2 spacecraft executed a flyby of a distant asteroid on Monday, marking a new operational phase for the probe. The encounter is part of a mission to gather data that could help protect Earth from potential asteroid impacts.
The spacecraft initially made history in 2020 by returning samples from the asteroid Ryugu to Earth. Now repurposed, it is collecting information on asteroid composition and trajectory, which scientists say is critical for developing planetary defense strategies.
According to The Japan Times, the flyby represents a shift from exploration to threat mitigation. No specific data or measurements from the encounter have been released yet, as analysis is ongoing.
The mission underscores Japan's growing role in planetary defense, a field long dominated by NASA. The data could inform future deflection techniques or early warning systems for hazardous near-Earth objects.
Experts caution that planetary defense remains a nascent science, and Hayabusa2's contributions will require years of analysis before they yield practical applications.
